Product Overview

The NSA9260X is an EMC-enhanced, AEC-Q100 compliant, highly integrated bridge automotive pressure sensor signal conditioning chip. It features a high-precision, variable-gain instrumentation amplifier and a 24-bit ADC for the main signal measurement channel, and a separate 24-bit ADC for auxiliary temperature measurement. With an integrated MCU, the NSA9260X supports second-order temperature drift calibration for sensor zero point and sensitivity, as well as up to third-order non-linear calibration, achieving an accuracy within 0.1%. Calibration coefficients are stored in a multi-programmable EEPROM. The NSA9260X offers overvoltage and reverse voltage protection, supports JFET high-voltage supply or direct high-voltage supply, and provides multiple output modes including analog voltage and PWM output, along with sensor diagnostic functions.
